A Secure Communication over Wireless Environments by Using a Data Connection Core

In this paper, we propose a new symmetric key exchange system, named the Wireless Security System with Data Connection Core (WiSDC for short), which can not only verify whether a user is a legitimate one or not, but also produce internally used parameters, named internal keys, and speed up the key exchange process for a wireless session as well. Moreover, the WiSDC adopts a pseudo random number generator, which has a feedback control mechanism, to generate more complicated keys for data encryption. Experimental results show that the WiSDC can effectively enhance the security level of a wireless environment.
